    摘要: A particular implementation for contrast enhancement for a group of images in a database uses locally linear embedding on the luma histograms of the images to capture the structure of the database through local linear relationships between images. Target histograms are determined based on the result of the locally linear embedding process. The columns of the target histogram matrices are used for each image within the database to enhance the contrast of the image.

    摘要: A method of taking a self portrait image using a mobile device having a front camera and a back camera includes capturing a self portrait image using the low resolution front camera of the mobile device as a reference image. A new image is then acquired using the high resolution back camera of the mobile device. The two images are compared for framing accuracy and the mobile device provides audio instructions to a user to adjust the position of the mobile device for more accurate framing. Another image using the high resolution back camera is acquired to more closely frame the high resolution image with that of the low resolution reference image.

    摘要: The invention relates to a method for sorting a group of images of a database, the images of said group being called example images and being associated to a same scene.
    According to the invention, said method comprises assigning (411) a score ( Score i ) to at least one example image of said group, said score ( Score i ) taking into account together:
    - a value ( V sci ,N sci ) representing a space correspondence between said at least one example image and a source image ( I s ) representing at least a part of the same scene as the example images of said group, and
    - a piece of information ( C D ,E,E i ,D color i ) representing at least a color distribution of at least one part of said source image ( I s ).

    摘要: A method and apparatus for controlling example-based image manipulation are disclosed where selection of example imagery and workpiece imagery is done with a pointing device (605). For increasing the efficiency of controlling, selection of an image characteristic to be transferred is derived from an interaction sensed on a second input device (603, 611, 612, 613, 614) during a motion time interval of the pointing device (605).
